Laszlo Ersek 5b080845a1 MdeModulePkg/RamDiskDxe: replace OpenFileByDevicePath() with UefiLib API
Replace the OpenFileByDevicePath() function with EfiOpenFileByDevicePath()
from UefiLib, correcting the following issues:

- imprecise comments on OpenFileByDevicePath(),
- code duplication between this module and other modules,
- local variable name "EfiSimpleFileSystemProtocol" starting with "Efi"
  prefix,
- bogus "FileHandle = NULL" assignments,
- passing a potentially unaligned "FILEPATH_DEVICE_PATH.PathName" field to
  a protocol member function (forbidden by the UEFI spec),
- leaking "Handle1" when the device path type/subtype check fails in the
  loop,
- stale SHELL_FILE_HANDLE reference in a comment.

Hao Wu 07a3fecd4c MdeModulePkg RamDiskDxe: Report ACPI NFIT for reserved memory RAM disks
The RamDiskDxe now will report RAM disks with reserved memory type to NFIT
in the ACPI table.

This commit will also make sure that an NVDIMM root device exists in the
\SB scope before reporting any RAM disk to NFIT.

To properly report the NVDIMM root device, one will need to append the
following content in the [Rule.Common.DXE_DRIVER] field in platform FDF
files:

RAW ACPI  Optional                |.acpi
RAW ASL   Optional                |.aml
